Hi Noesis,
So supposing I have a template class like this:

static constexpr const char sControlTypeName[] = "CustomControlType";
template <class Type, const char* Param = sControlTypeName>
class FCustomControl : public Noesis::UserControl
{};

How should I fill in for say

FCustomControl<float, sControlTypeName>

class type in this macro?

NS_DECLARE_REFLECTION(<?>, UserControl)

and

NS_IMPLEMENT_REFLECTION(<?>, "CustomControl")

These are what I have tried but just no success:

NS_DECLARE_REFLECTION(FCustomControl, UserControl)
NS_IMPLEMENT_REFLECTION(FCustomControl<float, sControlTypeName>, "CustomControl"){}

I'm not sure it is even allowed though.
Thanks.

Oh I tried:

NS_IMPLEMENT_INLINE_REFLECTION_(FCustomControl, UserControl, Noesis::IdOf("CustomControl<", Noesis::IdOf<Type>(), ">"))

and it compiles.

As you found the reflection for templated classes should be defined inside the class definition using NS_IMPLEMENT_INLINE_REFLECTION macro.
If you want to use those custom controls in xaml I suggest you use a name that doesn't contain '<' '>' characters, something more like:

NS_IMPLEMENT_INLINE_REFLECTION_(FCustomControl, UserControl, Noesis::IdOf(Noesis::IdOf<T>(), "CustomControl"))

Yeap, thanks for your confirmation! Indeed, if I use say "CustomControl<float>", there will be an error about some invalid token.
